Allowed? People over 18 are generally considered adults, so they can do anything they wish, law permitting, so there's no "allowed".
maybe
well if they like the show then it's okay for them.
And if they were married, or female, would that make them younger ?
Yes.
These teens & adults probably think you are too old to watch these or they think that those shows are stupid. Or possibly they are just being immature.
Adults still have a child in them, so it depends what they like.
no why?
no
I do not think so only if you want to that's all that matters
Nope
Atomic Betty was a 12 year old Canadian cartoon girl from Moosejaw Heights that fought as a Galactic Guardian. Johnny Test was an 11 year old cartoon boy with two genius sisters. Both cartoons were made by Warner Brothers.
Not at all. Part of us always remains a child. I asked my parents if adults watch cartoons, and they told me it depends what they like.
